摘要：

The use of integral viaducts, devoid of support devices and expansion joints in the rails, improves functionality and safety in comparison with traditional railway viaducts, while significantly reducing maintenance costs. However, regulatory requirements often hinder their implementation when fostering oversized conventional alternatives. High-speed railways are the transportation mode of the 21st century and the viaducts that support the tracks would be yet another manifestation of structural and technological progress. This paper presents some thoughts based on the Spanish experience in this type of structures.
